CONCRETE FORM.

Application -led February 21, 1927.. Seria-1 No. 169,943.

This -invention iielat-es te a form [designed primarily for use inproducing .checks tor irrigating ditches of that type shown, Vfor example, in my -c-o-pendling application ot even date herewith.

It is .an object of the invention to provide a collapsill le form which can beset up readily 'Por use -i-n an irrigatingditeh, the construction of the ttorlm being such that, after it. has been properly set up, concrete can be poured ther-cinto so as to produce a 'onepiece check extending along the bottom and up the sides of the ditch where it will constitute an eiiicient abutment for -a gate and a protection *for 'the 'bottom and walls 'of the ditch whe-re thefwater (flows over 'the gate.

il; further vobject is Ato vprovide a 'lporin of this character which is cheap to manufaes ture, light and durable, and can be readily set up tor use land easily *taken apart.

lilith the Vtoregoi-ng and other objects in view which will appear as the description proceeds, the invention resides in the com-- bination and arrangement ot parts and in the details ot construction hereinafter described and claimed, it'being understood that changes in the precise embodiment ot the invention herein disclosed may be made within the. scope ot what is claimed, with out departing from the spirit of the invention,

'ln the accompanying drawings, the preferred forms of the invention have been shown.

In said drawings:

Figure l is a front elevation of the form.

Figure l is a top plan view thereof.

Figure 3 is a section on line 3 3, Figure 2, the Jform being shown set up for use in a ditch.

Figure 4 is a section on line 4-4, Figure l, the form being shown positioned in a ditch.

Figure 5 is a section through the form on line :VP-5, Figure Ll.

Figure 6 is a section through a portion of one side of the form taken on the line 6 6, Figure 3.

Figure is a iront elevation of a portion of a forni provided with a supplemental plate tor retaining concrete.

Figure 8 is a plan view of a portion of the inodilied structure 'illustrated in Figure 7.

Referring to the figures by characters of reference l designates side panels formed space is provided between the of wood or any other suitable material having their i'ront and .back .edges converging upwardly as lshown at 2. Along :the ,outer side oi each. t these side panels are secured .cleats 3 arranged, at the edges ot the .panels parallel there Tith, the cleats ,tliieretor converging upwardly as will loe .obvious and as f.'.i'. t

'sn-own in l* lcure 2. To the bottom .portion x is .bolted ,or otherwise attached is `attached to a bottom strip 5 bridging the space between .the side panels l. Y'lhese :botetona strips 5 .are arranged in the saine planes as :the cleats to which they are attachedl and :are held against the lower edges of .the side panels as shown. Brackets 6 .or the like are attached to the panels l and `are conheeled 'by a Lbrace strip 7 extending troni .one sic-le :to the .other .olil the form. An .open lower edges of the-panels l. Y

In using the form a shallow depression is dug transversely within the bottom of an irrigating ditch D, this depression being shown at CZ. Additional depressions are formed in the sides ci the ditch at the ends ot the depressions cl as shown at e. The forni is then placed in position with the loottom strips 5 resting in the depressions d and with the cleats 3 resting in the depressions e. lilith the form thus located concrete is poured into the spaces between the side panels l and the cleats 3 and the dirt walls of the depressions c. Thereafter an additional quantity ol" concrete ispoured into the depressions Z and is leveled ott iiush with the top edges of the strip 5. This top surface of the bottom thus produced is preferably slightly below the level of the bottom of the ditch as will be apparent by referring to Figure el. After the concrete has set the form is removed, leaving a one-piece concrete check extending along the bottoni and up the sides of the ditch, the sides' oi the check converging upwardly, said sides in turn diverging upwardly relative to each other, and both sides being integral with the bottom of the check.

VShould the tormbe located at a point where the wall of the ditch cannot be used conveniently Ytor holding the concrete as it is poured between the cleats 3, a retaining member of wood, sheet metal or the like and which has been illustrated at 8 can be attached to the outer edges of the cleats 3 by' means ot clamps 9, bolts, or any other suit- Civ able devices. Thus the concrete will be properly retained when poured between the cleats. v

lVhen the form is not in use the straps a can be unlastened troni the bottom strips 5, the brace 7 can be detached troni thebrackets G, and the entire :torni collapsed into a sinall bundle which can be conveniently carricd.

The forni constituting this invention can have its side panels Ylorined ot sheet inetal, wood or any other desired material. lt forined ot sheet metal the cleats along the converging edges could of course be made integral with the panels.

lVhat is clainied is:

l. A forni ot the class described including side panels diverging upwardly and eachhaving upwardly converging 'lront and back edges, a brace interposed between and connecting the side panels, cleats upon the outer sides ot said panels along the converging edges thereof, and bottom strips connecting the cleats ot opposed panels, there being an open space between the bottoms ot the side panels.

2. A forni tor molding concrete checks, including upwardly diverging side panels havingupwardly converging edges, cleats upon the outer faces ot the panels and along operating with the side wall of a ditch toVV torni a concrete receiving space, and bottoni strips connecting the corresponding cleats of opposed side panels, there being an open space between the lower edges of the side panels, said bottoni stripscooperating to retain concrete poured into the space between the strips and.- beneath the lower edges of the side panels.

A iorin 'jor use in the production oi one-piece concrete checks for irrigating ditches, including upwardly diverging side panels each having upwardly converging edges, cleats upon the outer faces ot the panelsI along the converging edges, a brace interposed between and connected to the panels, bottoni' strips connected to the cleats and extending across the space between the side panels, and means cooperating with theV cleats and the side panels for torining concrete receiving spaces, there being an open space between the bottoni strips and the' lower edges ot the side panels to receive'concrete to torni the bottoni ot a check.
